Hi. we are currently looking at using 12V Lead Acid batteries for a small project and need to know if they can withstand the high draw of todays brushless ESC's without damaging the ESC.
is it possible to use them as weight is not an issue.
any help here would be greatly appreciated.
Well,they don't have great discharge rates.Will you be using 60 Ah car batteries?
nope. was thinking of using those smaller batteries. the 7AH ones.
Seems hard.
hi mate.
go for the wheel chair or golf buggy batteries, they are made for high discharge rates usualy get them up to 16 amh
they are gell battery........same construction as lead acid but leak/spill proof, you can use them mounted any way up so handy for fitting in smaller area

Try efymag.com , there is a project for landrover , using brushed motor which uses lead acid battery , u cant use usual RC radio with that project
You can use Lead Acid batteries, but I doubt the 7Ah ones will be upto the task. I guess its got to be a trial and error method for this one. Several engineering project vehicles running Brushless motor setups have been built using Lead acid batteries. You may not have out right acceleration, but the torque will be chassis twisting.
However, you can add a capacitor bank to the battery setup to account for the current draw. This will work and will help acceleration to a large extent. It all depends on the application.
What ESC are you planning to use?
